[PATCH 1/2] ath9k: fix misc debugfs when not using chan context

[greearb@candelatech.com]

From: Ben Greear <greearb@candelatech.com>

When channel-context is not enabled, all vifs belong to
the first context, but it is not configured as 'assigned'.

Fix misc debugfs file to print out info for non-assigned
contexts, and also print whether ctx is assigned or not.

This is not overly critical, but fixes regression in 3.17 kernel.
